TTC 3rd Child After Miscarriage

Hello I'm new here. A little about me we have two beautiful girls 6 and 4. We lost our 3rd baby Thanksgiving Day of 2013. It was the first miscarriage I've ever had and it was horrible. We were 10 weeks in. We just started TTC again this week. I'm nervous about another loss and how long it will take to conceive. Any advice on what to expect on a pregnancy after you've had a miscarriage anything special I should do this time around. Thanks
